I've honestly never paid much attention to racials. Maybe they are important for PvP, but for PvE I don't think it is. As a draenei you do get an extra little hot, so it is nice at times. Play what you want though.

For PvP, humans probably are superior; for PvE, the Draenei racial makes Ret reforging a little easier, but the human's bonus spirit likely makes healing a tad easier, the expertisemakes Ret reforging easier (considering numbers show an overabundance of hit in T14 gear and a distinct lack of expertise on current heroic 5-man gear), and the reputation bonus I imagine to be amazing considering how much of a grind the new MoP factions are. I play Dwarves almost exclusively, though, so this is really speculation on my part based on knowledge of class and game.

Draenei get +1% hit regardless of weapon type; humans are restricted to swords and maces if you wish to receive +1% expertise. Unless the best weapon you can get turns out to be an axe (or polearm, but those have exclusively been agility weapons for a while now), that's a wash. But it's a possibility, so small advantage: Draenei.

Draenei have a 3-minute-cooldown HoT that restores an amount equal to 20% of your maximum HP whether you use it on yourself or someone else. Honestly, given its cooldown, it's a drop in the bucket considering how much offspec healing capability paladins currently have in both Ret and Prot, but you still might find it useful. Humans have a 2-minute-cooldown CC breaker that shares its cooldown with PvP trinkets; between the racial and Divine Shield (with /cancelaura macro) you can break out of annoying stuns at least 7 times every 10 minutes. IMHO, big advantage: Human.

Humans also receive a 3% bonus to Spirit, a nice regen boost if you spec into Holy. Draenei also get a bonus to jewelcrafting and take 1% less shadow damage. Humans grind reputation 10% faster with Diplomacy.

I think the racials are biased quite in favor of humans, who essentially retainin the Draenei's hit bonus (in expertise form -- unless your weapon isn't a sword/hammer/mace), can break out of CC to maintain aggro and reduce damage while tanking (avoidance drops to 0% when you're stunned) as Prot or simply increase dps uptime as Ret, have higher mana regen as Holy, and grind reputations faster.

Male Drae make awesome looking tanks. Their animations just scream arrogance, which is very appropriate when you consider the type of character a tank should be. I wish I could still have my old Drae Prot Paladin on the Horde side.

How can you even consider going male draenei. Unless you want everyone to automatically think you are terrible at this game and enjoy looking at a big space goat then go ahead. Seriously ive never seen a semi decent male draenei at this game. Just like male night elfs.
